For any OpenFlows product, after computing the model, when a custom report is saved / exported, a file with .PRNX extension is created. How can this file be opened?
This is a report file created when you save or export the custom reports for any OpenFlows product . This file can be opened through PondPack (or the OpenFlows product that you are using) by going to the Report pulldown menu. Choose any report listed here, such as Project Inventory / Scenario Summary. Once this report is open, you can click the Open button at the top of the report. The extension that the Open dialog is looking for is the .PRNX file extension, allowing you to open the report file.
